um: Fix the -Wmissing-prototypes warning for __switch_mm
[ Upstream commit 2cbade17b18c0f0fd9963f26c9fc9b057eb1cb3a ]
The __switch_mm function is defined in the user code, and is called
by the kernel code. It should be declared in a shared header.
Fixes: 4dc706c2f292 ("um: take um_mmu.h to asm/mmu.h, clean asm/mmu_context.h a bit")
